Liquid cooling question

[Jrobertson]

Hey guys so today I was dusting my cousins PC with compressed butane. I noticed if I shaked the can it would get cold, very cold. I continued to play around with it and noticed it can actually temporarily freeze water. So getting to the point is this stuff viable for LC? (I know butane is flammable but it would never reach the correct temperature for it to set a light) Paired with copper tubing I can see a very promisng cooling solution.

no, just no, how would you keep shaking it? with a robot arm? you do know that energy is coming from somewhere so you will have to refill the butane and such, not a cheap way to cool your pc...

Think it's called Phase Change cooling dont know for sure, but it would be inefficient as its about the pressure change in the can so you would need to compress the gas repeatedly

I understand what your saying but wouldn't the general motion of the loop replace the need to shake it?

Why clean your pc with butane in the first place?

The air duster he bought was butane

its the molecules inside the can that need to get energy from shaking,

 

(im no expert tho but i have quit alot of chemistry classes (4 hours a week) so i think i can make an educated guess)

if you looking for a good idea for liquid cooling look up Freon liquid cooling. Its the stuff that cools your fridge/icebox. This guy shows how he did it on youtube. http://www.youtube.com/watch?v=OWKG4F8ANu4

Phase Change cooling is many times more effective than water cooling (that is not actually what shaking a can of butane does but you want something better than watercooling so here it is). Basically it takes a refrigerator unit and cools your CPU with it. Those things are very expensive but they work very well. They change liquid from a gas to liquid then back again to rapidly cool the CPU. I am not altogether sure I understand how exactly it works but you get very low temps from it. However the unit itself is pretty loud.

Also something being cold does not make it ideal for liquid cooling. Water is effective because it can hold a lot of heat and move it around. A cold liquid is only cold for a short period of time before it either changes to a gas or just resides at room temperature.

Please stop shaking cans filled with compressed gases, it's dangerous. 

 

This wouldn't end up being a very effective way of cooling your computer. How would you do it? Are you thinking about running butane through the copper tubing?
